To enhance the gene transfection efficiency to targeted cells while reducing the side effects to untargeted cells is of great significance for clinical gene therapy. Here, biodegradable highly branched poly(beta-amino ester)s (HPAESS) are synthesized and functionalized with folate (HPAESSFA) and lactobionic acid (HPAESS-Lac) for targeted cancer cell gene transfection. Results show that because of the triggered degradability of the vector and enhanced receptor mediated cellular uptake of polyplexes, the HPAESS-FA and HPAESS-Lac exhibit superior gene transfection capability in specific cancer cells with negligible cytotoxicity, pointing to their promise as targeted vectors for efficient cancer gene therapy.
